The Quality of Five Natural, Historical Italian Cheeses Produced in Different Months: Gross Composition, Fat-Soluble Vitamins, Fatty Acids, Total Phe…
2022
Simple Summary For the purposes of raising awareness of five historical cheeses of Southern Italy that are less known by consumers, and of restoring dignity to the breeders and producers of these cheeses, we studied their quality in terms of chemical composition, monounsaturated fatty acid (MUFA), polyunsaturated fatty acid (PUFA), conjugated linoleic acid (CLA), PUFA-ω6, PUFA-ω3, α-tocopherol, retinol, cholesterol, polyphenol content (TPC), total antioxidant capacity (FRAP and TEAC), and health index (GHIC). Two stretched-curd bovine cheeses, Caciocavallo Palermitano (CP) and Casizolu del Montiferru (CdM), two ovine cheeses, Vastedda della Valle del Belìce (VVB) and Pecorino Siciliano (PS)…
Analysis of lipids in pelagic fish of Sicilian Channel and use of fatty acids as bacterial contamination markers
Lipids provide the expendable form of energy in marine ecosystem, and have an important role for the reproductive biology of fish. Also, lipids are important nutrients, versatile markers for marine trophic studies, bacteria markers etc. Among the lipids, several essential fatty acids are determinants for ecosystem health as well as for their known nutritional properties and prevention capacity of chronic diseases. Furan fatty acids (F - acids) are other important lipid bioactive compounds; for these is hypothesized a crucial nutritional role that is synergistic to polyunsaturated fatty acids omega 3 (PUFA ω 3), also if their mechanism is not yet clear. Source of essential fatty acid is the …
Caratterizzazione del pattern lipidico e degli acidi grassi del muscolo dell’ibrido Acipenser naccarii (Bonaparte, 1836) x A. baerii (Brandt, 1869) e…

Muscle phospholipids and tryglicerides were measured in two sturgeon (Acipenseridae) hybrids. Fatty acid composition of the two lipidic fractions showed a strong similarity between the two hybrids.
Lipid and fatty acid biomarkers as proxies for environmental contamination in caged mussels Mytilus galloprovincialis
2015
Mussels (Mytilus galloprovincialis) were transplanted from a reference site (Syracuse harbour) to an impacted site (Augusta Bay) from January to July 2013 to assess the biochemical response of caged mus- sels to high trace element and polycyclic aromatic hydrocarbon (PAH) contamination, using lipid and fatty acid (FA) biomarkers. Sediment and mussels were analysed to assess contaminant bioavailability in the study sites and bioaccumulation in mussel tissue. Trace elements (As, Cd, Co, Cr, Cu, Hg, Mn, Ni, Pb, V, Zn) and PAHs were significantly higher in mussels from Augusta than in those from Syracuse, mirror- ing the different environmental contamination. The biological impact quotient (BIQs…

Organotin(IV) and simple fatty acids: preliminary assessments
2012
Our group has a long researching tradition in the field of organotin(IV) complexes, usually proposed and tested as potential anti-tumor drugs. The leitmotif has usually been the modulation of the intrinsic toxicity/cytotoxicity of the organometallic moiety and a modulation of the toxic effect by means of biologically related molecules (synthetic or natural). Such a modulation is usually achieved by two (often overlapping) routes: dampen the damaging effects of the metal core, and serving as a carrier for specific tissue districts. Since a too tight binding on the organotin moiety is not always desirable – a too much stable complex could be a non-active one – carboxylates have always played …
Rheological and nutritional profile of spaghetti and bread fortified with hemp flours
2022
In recent years, the demands of food consumers have changed considerably. Food today is not only intended to satisfy hunger and provide the necessary nutrients, but also to prevent food-related diseases and improve the physical and mental well-being of consumers. Functional foods are formulated to contain healthy components, which when consumed daily as part of the diet, can have beneficial health effects. Cereal-based products, especially pasta and bread, are well suited for adding nutrients. Both bread and pasta, traditionally produced using durum wheat flour, can be prepared also using "non-wheat flours" in variable percentages or by incorporating food by-products, capable of increasing …
Ketogenic diet as antiepileptic therapy: Neurotrasmission effects
2017
The Ketogenic diet (KD) presents many effects on neurostrasmitters pathways. KD may act on potassium channels sensitive to ATP (KATP), inhibiting rapamycin pathway in mammalians or glutamatergic synaptic transmission or mediated by peptide hormones.
Age-associated changes in circulatory fatty acids: new insights on adults and long-lived individuals
2022
Long-lived individuals (LLIs) are considered an ideal model to study healthy human aging. Blood fatty acid (FA) profile of a cohort of LLIs (90–111 years old, n = 49) from Sicily was compared to adults (18–64 years old, n = 69) and older adults (65–89 years old, n = 54) from the same area. Genetic variants in key enzymes related to FA biosynthesis and metabolism were also genotyped to investigate a potential genetic predisposition in determining the FA profile. Gas chromatography was employed to determine the FA profile, and genotyping was performed using high-resolution melt (HRM) analysis. Blood levels of total polyunsaturated FA (PUFA) and total trans-FA decreased with age, while the lev…
